Hello,
I don't know if this is the correct forum but I am having trouble with the pto on a b-165. It won't disengage. I have adjusted it according to the manual with no luck. There appears to be a small oil hole on the outside and squirting oil in that helped for a while. This is the only vertical shaft machine I have so I am not really familiar with them. I can tap the lower part of the pulley with a brass hammer and it will release but once I engage it, it is stuck until I do that again. I would not mind taking it apart but I would be working on my back underneath and so would like to know anything I can about them before I try that. Would appreciate anything you can tell me.
